Greg,
domainA.com is the virtual site. domainB.com is only in DNS MX domainB.com -> mail.domainA.com When you send mail to user@xxxxxxxxxxx it works. When you send mail to user@xxxxxxxxxxx it fails with this error: ----- The following addresses had permanent fatal errors ----- <user@xxxxxxxxxxx> ----- Transcript of session follows ----- 553 mail.domainA.com. config error: mail loops back to me (MX problem?) 554 <user@xxxxxxxxxxxx>... Local configuration error
The way I understand what you are saying is that you provide DNS for a site that is not on your server but you want to accept the mail on your server, right?
They way I've done this is to setup domainB.com as a virtual site in the gui. Don't put anything under mail server alias. In the MX record then domainB.com >> domainA.com
In the gui for domainA.com put domainB.com as a mail server alias.You can setup the users at domainB.com and have the mail forwarded to the domainA.com usernames.
Don't know if this is the "correct" way to do it or not...but it works for me.You might also check out: http://list.cobalt.com/pipermail/cobalt-users/2001-February/034640.html
